descriptionThe ’ABTH162245 devices are 16-bit noninverting 3-state transceivers designed for synchronous two-way
communication between data buses. The control-function implementation minimizes external timing
requirements.
These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission
from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control
(DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively
isolated.
The A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 25-Ω series resistors
to reduce overshoot and undershoot.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABTH162245 is characterized for operation over the full military temperature range of –55°C to
125°C. The SN74ABTH162245 is characterized for operation from –40°C to 85°C.
